Milbank U5101-RL-38GBGR-KK-5T – Frequently Asked Questions

1) What is the difference between the two Milbank U5101-RL RV pedestal versions?
Both are 5 terminal ringless sockets with horn bypass. One ships as U5101-RL-38GBGR-KK-5T with a 100A main breaker and 620GB / 520GR receptacles; the other is U5101-RL-76GBGR-KK-5T with no main breaker and 1450GB / 520GR receptacles. Pick the breakered version if you want main disconnect protection built into the pedestal, and the no-breaker version if the main is handled upstream and you want the 50A RV outlet.
2) Will a 5 terminal meter socket work for my utility, or do I need 4 jaw?
The Milbank U5101-RL is built with 5 jaws for single phase service up to 240 volts AC at 60 hertz, which is the configuration many utilities require for network or 120/240V three-wire metering with a neutral terminal. Utilities specify jaw count and bypass type, so confirm with your serving utility that a 5 terminal ringless socket with horn bypass is on their approved list before setting the pedestal.
3) What size service conductors can I land in the Milbank U5101-RL?
Line side lay-in terminals accept 6 AWG through 350 kcmil, so you can feed it with anything from a small 60A branch feeder up to a full 125A copper or aluminum service conductor with room to spare. Lay-in terminals mean you drop the conductor in rather than threading it through a hole, which is faster on stiff 4/0 or 350 kcmil aluminum.
4) Is the Milbank U5101-RL meter socket rated for outdoor installation in an RV park?
It is UL Listed and Type 3R rated, which is the rain-tight enclosure rating used for outdoor service equipment. The enclosure is G90 galvanized steel with a powder coat finish, and internal insulation is glass polyester. That combination is what you want on a pedestal sitting in weather year round.
5) Does the Milbank U5101-RL include receptacles and branch breakers, or do I buy those separately?
It comes configured as a single power head with 3 receptacles and 2 branch circuits, plus a ground bar for equipment grounding. The specific outlet set depends on the version: the 100A main breaker build carries 620GB and 520GR devices, and the no-breaker build carries 1450GB and 520GR.
6) Can this Milbank RV power unit be fed from underground, or is it overhead only?
Either. The U5101-RL is built for overhead or underground cable entry and comes with a small hub opening, so an overhead drop lands through the hub and an underground lateral comes up from the bottom. For a typical RV park pedestal on a buried feeder, the underground route is the one you'll use.
7) Why pick a horn bypass socket instead of a standard no-bypass meter socket?
Horn bypass lets the utility or an electrician jumper around the meter so the meter can be pulled and changed without dropping power to the loads. On an RV site with occupied rigs or on anything feeding cold storage, event power, or life-safety loads, that is the difference between a meter swap and an outage. If the service can be shut down freely and the utility does not require bypass, a plain socket is simpler.
8) Can I use this Milbank unit for 208V three-phase RV sites?
No. The U5101-RL is a single phase device rated up to 240 volts AC, 60 hertz. For three-phase park service you need a three-phase socket or pedestal; this one will not meter or distribute a three-phase supply.
9) Is 125 amps enough for a single RV site pedestal?
Yes for a standard site. The socket carries a 125 continuous ampere rating on single phase up to 240V, which covers a 50A/240V RV connection plus a 30A and a 20A convenience outlet on the same power head. If you are feeding multiple pedestals from one meter point, size the service separately rather than loading this single power head.
